Remembrance Aloud after Prayer is a Sunnah

Question :

What is the ruling on raising the voice when seeking forgiveness and uttering remembrance after prayer, bearing in mind that this disturbs the others, since they find difficulty in maintaining a sense of humility in Tasbih and remembrance. Also, it is difficult for those who are completing their prayers to do so with humility and contemplation?

Answer:

The Sunnah is to say it aloud, as the Prophet used to say it aloud. Ibn 'Abbas said: "They used to raise their voices when making remembrance after finishing the prayer in the time of the Prophet." And if all of the people raise their voices, they will not disturb each other, but they will disturb each other if some of them say it aloud and others say it quietly. There is no doubt that it will disturb the one who says it quietly, but if he were to raise his voice like them, there would be no disturbance. As for those who are making up what they missed, they have brought it upon themselves; if they had wished, they could have come early and it would not have disturbed them. And as I said, if all of the voices were mixed together, there would be no disturbance, even for those who are making up their prayers, just as you see now on Fridays, the people all recite the Noble Qur'an and they raise their voices, but in spite of this, the worshipper comes and prays and he does not experience any disturbance.
